Summary
The .nav-item div around each navbar link currently has an explicit cursor: pointer style. However it's slightly higher than its contained link. This makes the styling undesirable since it tricks the user into thinking that they could click there to follow the link.

1. This pull request removes that style. It remains present on the link itself through the user agent stylesheet.

2. Interactive nav items without any links (currently only dropdowns) should still be receiving their cursor style independently. This is also done by this pull request for the .dropdown-wrapper class.
